Windows Odbcconf Load DLL
- source: splunk
- technicques:
- T1218.008
Description
The following analytic detects the execution of odbcconf.exe with the regsvr action to load a DLL. This is identified by monitoring command-line arguments in process creation logs from Endpoint Detection and Response (EDR) agents. This activity is significant as it may indicate an attempt to execute arbitrary code via DLL loading, a common technique used in various attack vectors. If confirmed malicious, this could allow an attacker to execute code with the privileges of the odbcconf.exe process, potentially leading to system compromise or further lateral movement.

Windows Odbcconf Load Response File
- source: splunk
- technicques:
- T1218.008
Description
The following analytic detects the execution of odbcconf.exe with a response file, which may contain commands to load a DLL (REGSVR) or other instructions. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line arguments. This activity is significant as it may indicate an attempt to execute arbitrary code or load malicious DLLs, potentially leading to unauthorized actions. If confirmed malicious, this could allow an attacker to gain code execution, escalate privileges, or establish persistence within the environment.
